          Components: serialization, snapshot

Export data shouldn't fail if an exception is encountered while exporting a single entry

Currently RegionSnapshotService save fails while deserializing the value before writing it to the snapshot file.

This causes the export to abort.

Instead, it should log a warning in this case and skip the entry.
